Strange noise from VR6

Recommended Posts

Talk about running out of luck....

 

Got back last night and the VR didnt sound right - popped the bonnet and its making a strange whirring noise from the left hand side of the engine (ancillary belt end)... anyone got any suggestions as to common things that need replacing in that area?

 

And to top it I whipped out the number one spark plug (see earlier thread! - chugging VR6) to find it covered in wet black substance again - smells like petrol.... duff leads perhaps?

 

I NEED to get these probs sorted for rolling road on 27th!!! ARGH!

 

Cheers,

 

Scott

Mine makes the same whirring noise as yours does. Haven't investigated it yet as it only does it when hot, so not too concerned. Might just be the bearings in the tension roller or something.....It might also be the timing chain as noise from that can be transmitted through the block to the alternator end. 100K is the norm for these but not unheard of for them to wear earlier.

 

Probably a HT lead with your other query, try swapping one over (completely, not just at the plug end!).

Yeah mine only does it when hot too funnily enough - but from what have been told so far it is a possibility the water pump bearings are noisy.... I dont like noises that arent supposed to be there....*:)... it isnt timing chain - I know what one of them sounds like when gets noisy *:)

 

Im pretty convinced its either pump or tensioner - going to take a more detailed look later and poss take off belt and have a feel of the bearings *:) ooer *:)

 

LOL - just swapping over at plug end will result in mis firing *;)

 

As for tempting fate - no comment *:)

Oh yeah, hadn't thought of the water pump. You're probably right on that one. Let me know how it goes cause I wan't to get rid of my noise too!

 

What kind of job is it to change out the pump? I've already bought 3 tubs of G12+ for when I pull the radiator out to fit the oil cooler, so would be a handy time to do it.

Well its not a hard job but is very time consuming hence why garages will charge alot for the job even though pump is only £30.... you need to do the following:

 

- remove airbox, etc

- remove drivers side front wheel

- remove inner wheel arch liner..

- jack up car and support it

- take weight off front and rear engine mounts

- remove bolts from engine mounts

- jack up engine using gearbox mount as pivot so engine should come up at an angle - jack up engine approx six inches so can get to pump

- undo bolts for belt,etc.. you might need to jack up couple of more inches.

- pry pump out of block and replace with new one.

 

Then stick it all back together....

 

VW quote 2hrs to do this... yet most garages take 4hrs... hence the labour...

Sounds a bit of a chore! Is that pump price from VW or G&S?

 

Cheers

Kev

 

Price is from GSF... no idea about price from VW but wont be much more would have thought....

How are you getting on with the noise? I traced mine and it was just the belt, so sprayed it with some silicon maintanence spray and it's quiet now. The only noise I've got now is some tapping from a couple of lazy lifters. It's just one thing after the next with these cars!!

Well I have tried to trace it without luck - a couple of back street garages reckon its the timing chain - I dont think it is as they make clattering noises not whirring noises *:) - going to book it into Specialist for service shortly so they can have a look for me then! *:)

Oh well, well good luck with it anyway mate and I do hope it isn't the wretched chain. Might just be a worn chain tensioner and not the chain itself? Have you tried spraying the alernator belt? That did seriously totally silence the noise, it was more of a chaffing/whir than a rattle, like you say.
